The opening in the second drawer didn't take into consideration any joint configuration except a straight back line-up. I had to hire a carpenter to adjust the drawer to fit. The vanity won't fit flush against the wall unless the wallboard and quarterwood are cut to accommodate the vanity.  The back had to be removed and tossed to allow for these modifications. The manufacturer built this for one very narrowly defined fit. If you buy it, you will need to make many modifications.
